Very yummy, but I recommend NOT chopping up the peppermint crisp bars which is a very messy process and requires a knife and chopping board. Rather, they are EASILY broken up with your fingers while still in the packet! No mess, no fuss! Also, using my 21.5cm square slice tin the white chocolate layer was way too thick and difficult to cut through (my own fault for using a smaller tin). I would make this again, but adjust white choc for my tin next time. Thank you for this recipe, Lauren!
Petra
This is delicious and so easy to make
Lauren Matheson
Thank you!
Jessie
I usually have trouble with slices. Instructions were clear, it turned out perfectly and tasted delicious. My new go-to. Thanks
Milli Troon
Insanely sweet and delicious. Looks great, quick to make. I used a block of peppermint chocolate with the gooey centre and worked great. I’d forgotten just how awesome peppermint crisp bars are, lovely to rediscover them.
Denise Fitzpatrick
Very easy and extremely tasty. Highly recommend to take along to any get-together but advise you have copies of recipe printed to hand out !!
Natalie
Hi Lauren! Thanks so much for sharing. For the 200g peppermint chocolate, do you mean peppermint crisp chocolate?
Also how should these bars be stored and how long would they last?
Thanks again, from South Africa <3
Lauren Matheson
Hi Natalie, I use the Cadbury Peppermint filled chocolate blocks, however you can use peppermint crip bars too. I keep this slice in the fridge for up to a week. I hope that helps 🙂
Natalie
Thank you so much Lauren! Much appreciated! I can’t wait to try these out for Christmas 🙂
Carine
Hi Natalie, you could use a mint Aero block, or peppermint-filled squares block. You only need 180g of peppermint chocolate =)
Kerry
This was so quick and easy for the school cake stall. I replaced the Peppermint Crisp in the slice, for another block of cut up peppermint chocolate pieces, and then sprinkled extra Peppermint Crisp over the top of the slice. Everybody loved it!
Lauren Matheson
I’m so glad it turned out so well for you x
Ange
Are you able to freeze this? Such a yummy recipe – thank you. X
Lauren Matheson
Hi Ange, I haven’t tried freezing this one before I’m afraid. I’d just be a little cautious about how the chocolate would go when defrosted.
Lorraine

Lindy Buckley
